Looking at options for winch and lighting wiring on here, and ran across a lot of useful information. But I have a question…and would like to get the input of those more versed with these machines than I before I create a potential electrical problem.

I have ordered the harness from my favorite parts supplier, and am waiting for it to arrive. The question is simple: how much load on the sub-harness is too much? I plan to use the keyed power from the harness to supply only switch power for 3-4 accessories: winch switches (handlebar and remote), and two light bars (72W front, 36W rear). Only switch power will come from the factory sub-harness, full battery power will run through relays activated by power from the switches/sub-harness.

Not really interested in installing an auxiliary fuse block at this time since the winch and lighting are all I plan on adding to the electrical system for the foreseeable future. Considering that it is fully possible/probably that all 3 relays will be engaged at the same time, would the power required for them be too much for the sub-harness?

Thanks for humoring a noob…
